I am sure in a memo like this they need to lay out all the practical business reasons why their company should make this move, but ever since this news [1] came out in 2019 I've suspected that Ring had other uses to the then richest man in the world, as a massive private surveillance system.

"Beginning in 2016, according to one source, Ring provided its Ukraine-based research and development team virtually unfettered access to a folder on Amazon’s S3 cloud storage service that contained every video created by every Ring camera around the world."

Now, you can easily imagine that this started as some engineers' innocent attempt to improve their machine learning algorithms. But at the same time, this system was purportedly active at the time of the Amazon acquisition, and while there is no way to prove their motives, this seems to me like a huge perk for someone who is one of the most powerful people in the world.
